These are the quotes I think most people are replying to. You are basically saying that the tool is good for nothing, not exact words, but reading into it. last one to use, leaves lumps...
To answer your last statement,
it is not that is not needed, like rasps might not be needed, or sandpaper, it is that if used right it is an invaluable tool for removing stock fast, accurate and easily. All tools have their place, a rasp removes stock fast, but mostly on a small area at a time, while with the spoke you can go the entire length of the neck.
In the end, I like to use all tools available, Only once I have use a spokeshave (thanks to Hyunsu), and I will be buying one as soon as taxes come over.

One tool is not mentioned here and I liked a lot while working at Hyunsu's is a carving knife, this one he made from a broken file. Both the heel and the volute were shaped using it. It took me a while since this was MY FIRST neck, but while I carved both my heel and volute, he did an entire neck (except for final sanding). This was in less than an hour.
I understand your point, but your first post was done unfounded and by personal opinion, a lot of bad advise has been given like that, and this is why most of the time, if I have limited experience I try to stay behind and wait until the most knowledgeable guys post to corroborate my ideas.
